2.3 FUSES
The protection of the CFW900 is in accordance with the CFW900 – User Manual, available on the WEG website.
2.4 ACCESSORIES
For further information, refer to the User Manual of the respective module.
2.4.1 Output Reactor (According to the Inverter Rated Current)
The use of a three-phase load reactor adds an inductance to the inverter output to the motor. That lowers the dv/
dt (voltage change rate) of the pulses generated at the inverter output.
The maximum cable length with reactor is 500 m.
The maximum cable length with sinusoidal filter at the output is 5000 m. Electrical representation:

2.4.2 Selector Switch for Operating Mode (Local / Remote)
The function of the local/remote selector switch "S3" is to select the operating mode of the drive, either local
operating mode or remote operating mode.
These accessories are all from the WEG CSW line, using auxiliary contact blocks (BC10F and BC01F), AF3F flange
and pushbutton (CSW-CKxxxx) or selector switch (CSW-CAxxxx).

2.4.3 CANopen/DNet Communication
CANopen/DNet module (CFW900-CCAN-W).
Every device on the CANopen network must have an address between 1 and 127. This address must be different
for each device.
Devices with CANopen interface generally allow the configuration of the baud rate, which depends on the length
of the cable used in the installation.
